SCAD_soft_thresholding: SCAD soft thresholding function

In DavidKLim/FSCseq: Feature Selection and Clustering of RNA-seq Count Data

Description

Takes pairwise distances between cluster log2 means and penalty parameters lambda and alpha, and imposes SCAD thresholding rule

Usage

SCAD_soft_thresholding(diff_beta, lambda, alpha)

Arguments

diff_beta	difference in pairwise cluster betas (log2 means)
lambda	numeric penalty parameter, lambda >= 0
alpha	numeric penalty parameters, 0 <= alpha < 1

Value

diff_beta value, after SCAD thresholding rule is applied

Examples

beta1=1
beta2=2
SCAD_soft_thresholding(beta2-beta1,0,0)
SCAD_soft_thresholding(beta2-beta1,0.5,0.45)
SCAD_soft_thresholding(beta2-beta1,1,1)
